Refractory materials for lime kilns
Refractory materials for lime kilns are selected according to different kiln shapes and actual uses. Types of kilns for producing activated lime include rotary kilns and shaft kilns. Generally, there are co-current regenerative two-chamber shaft furnace, double beam shaft furnace and ring tube shaft furnace.
I. LIME KILL STRUCTURE
Lime kilns are mainly composed of kiln body, feeding device, preheater, distribution, combustion area, cooler, ash discharge, and dust removal.
Since the physical and chemical interactions between materials and gases in different parts of the kiln are different, the requirements for refractories used in different kiln areas are also different.
II. THERMAL INSULATION MATERIALS FOR LIME kilns
1. Samoot H1 refractory bricks
It is a type of Sa mod refractory brick with standard sizes H1, H2, .... mass produced. The product is widely used in the construction of furnaces, carts, etc.
2. CR-65LC refractory concrete
Refractory temperature: From 1500 - 1650 degrees
Ingredients: Refractory cement and refractory aggregates (Samot grit, aluminum grit, granular plunin and additives when used)
3.  Ceramic fabric:
Ceramic fiber fabric is a textile fabric manufactured from high purity Alumino-silicate based ceramic fiber, reinforced with fiberglass and optional alloy steel wire. Ceramic fabric is white and odorless, suitable for high temperature applications up to 2,300°F
4. Ceramic cotton:
Ceramic wool in roll form is a product made of ceramic fiber, in roll form, with the ability to insulate and withstand high temperatures from 1260 degrees and 1430 degrees Celsius, especially used for kilns, ceramic kilns, and smelting furnaces. steel, ceramic tile oven, bread oven, fireproof door,...
